IP Video Surveillance Solutions for Airports
Modern video surveillance in airports requires flexible solutions which fulfil stringent quality and security demands: Distributed cameras, recording and transmission of video signals, live presentation, use of digital networks, intelligent picture processing, integration of audio channels and control as a video system via a higher-order (often already existing) building-management system
Due to the layout of modern airports with numerous separate buildings and areas, the need arises for multi-area surveillance systems with the flexibility to set up secondary control centres as well, for example. Emergency scenarios and the integration of mobile control stations also play an important role e.g. iPhone/iPad
Picture Generation
The security requirements at airports are extremely high. Whether on the airfield or in the hangar, the terminal buildings, car parks or access roads: At airports, huge premises with a variety of areas must be monitored around the clock. In particular, expansive areas such as airfields are especially challenging for video surveillance. In the past, in order to adequately monitor the entire area, it was necessary to use a number of cameras installed in a whole range of locations. Dallmeier's multifocal sensor system Panomera®, however, represents an entirely new technology and a fundamentally different approach to the issue of video security
Panomera® is a unique HD camera technology, which was especially developed for the video surveillance of expansive areas. Panomera® guarantees highest detail resolution at every distance. Whereas conventional megapixel cameras have a definite disadvantage: The farther you zoom into the picture, the higher the loss of detail, causing the picture to become blurry
The multifocal sensor system Panomera® stands out due to its completely new lens and sensor concept: The resolution never falls below the specified parameters, not even in the most distant areas of the image. Therefore the Panomera® effect guarantees a uniform resolution over the entire scene. This way, even objects that are farther away can be displayed with the same resolution quality as objects in the foreground of the picture
In conjunction with other Dallmeier high-resolution IP cameras, this technology fulfils all the requirements of modern camera technology and is especially well suited for use in highly complex video surveillance systems of airports, with their wide variety of operating conditions
Due to their very large dynamic range, Dallmeier cameras are ideal for use in airport terminals, for example, in which a variety of lighting conditions (including direct sunlight) are found over the course of the day due to large-size glass facades. Difficult lighting conditions of this type are also dealt with in the loading and unloading zones of freight terminals. At city-train stations, the cameras also provide picture material which is highly suitable for secure surveillance of the platforms, even in backlit conditions
Dallmeier IP cameras are used with intelligent video-sensor technology in the field of outdoor security. Last, but not least, suspicious people and vehicles are reliably detected and the security control centre is alerted, even in rain, hail or snow, due to the excellent quality of the picture material generated
In conjunction with Dallmeier picture transmission and recording technology, the operator is in control of a complete video security system with the best components, fine-tuned to one another, from one source
Picture Processing - Picture Processing - Picture Storage
The Dallmeier product range offers the most modern solutions for the requirements of today's airports. By using the Virtual Matrix and the numerous Intelligent Video Analysis Systems (from people counting to abandoned suitcases in the terminal area), solutions ensuring maximum security are created
The Virtual Matrix from Dallmeier enables the transmission and recording of video and audio signals in broadcast quality via an Ethernet/IP network. Using this technology any number of cameras at an airport can be analysed, recorded and, if necessary, transmitted via the IP network. The implemented video compression enables camera pictures to be transmitted in real time and with the best possible quality and frame rate, even allowing convenient control of PTZ cameras. Recording also occurs in broadcast quality into a ring memory, which is automatically overwritten after a preset time has passed - e.g. 14 days
Intelligent video analysis systems from Dallmeier are especially suitable for outdoor applications, e.g. for fence surveillance. They can analyse relevant video pictures and, for example, identify a person moving in a certain direction within a certain area as suspicious and alert the higher-order management system. The live picture is then switched to one of the video surveillance monitors by the Virtual Matrix. The most modern algorithms, such as object classification, ensure that the false alarm rate from ambient environmental influences is minimised
In addition, the SEDOR® technology is also available for use inside the terminal or in the baggage claim area. It enables amongst others the monitoring of static objects and can alert the central security office if, for example, a suitcase was set down in a critical area and left for a longer period of time
All Dallmeier devices can be integrated into the system network and enable simultaneous recording and playback of any connected camera via the time-shift method. PTZ functions can be used. Additional functions, such as slow-motion playback, scalability of picture quality, numerous playback functions and integrated picture filters for improvement of picture quality (e.g. with noisy camera signals) show the range of capabilities of our devices and predestine them for use in airports
Dallmeier provides a variety of management systems for control of all the devices, and also different interfaces for integration into an existing infrastructure
Using DDNS Service & Dynamic IP Addresses in Surveillance Systems
Most users of surveillance systems want to be able to view their cameras remotely over the Internet. In order to do this, a high speed Internet connection must be available both at the location of the surveillance system and the location where the user wants to view the cameras remotely from. If you have a cable or DSL Internet connection, your Internet service provider (ISP) may be assigning your Internet connection a static or dynamic IP address. This article will first discuss what the difference is between the two and then how it affects installing a surveillance system with remote viewing capability.
- Static IP Address – A static IP address is used when your ISP always assigns your cable or DSL modem (your Internet connection) the same IP address every time the modem connects to the Internet service.
- Dynamic IP Address - A dynamic IP address is used then your ISP may change your IP address anytime you connect to the Internet
.
When installing a business or home surveillance system including a network-able DVR, it is important to know whether you have a static or dynamic IP address if you intend on using the network / Internet capability of the DVR. The networking functionality of the DVR allows you to make a remote connection to your DVR over the Internet so that you can control the system and view your security cameras remotely.
If you have a static IP address at the location of your DVR, you can always connect to your surveillance system remotely using the same IP address. If you have a dynamic IP address, things are a little bit more complicated because you never know when your IP address is going to be changed by your ISP. In order to keep track of any changes to the dynamic IP, you will likely want to subscribe to a dynamic DNS service (DDNS) that keeps track of it for you. The most popular DDNS service is dyndns.com and lucky for everyone, it is a free service.
When you register with a DDNS service, you can create a host name, for example something like “mydvr.ddns.org”, just like the domain names and hostnames that you use to access a website on the Internet. You then associate that host name with the IP address of your Internet service connection. One way this can be done is by using a router that supports DDNS. Most routers on the market do. Log into your router and locate the DDNS setup screen. The location will vary by router manufacturer. Enter your DDNS account settings, including your login, password, and the host name that you registered. Now, anytime your router detects that your IP address has changed from your ISP, the router will notify the DDNS service about the change by telling it what your new IP address is. This allows you to always use the hostname that you registered to connect to your DVR remotely over the Internet. There is no need to remember or keep track of your IP address

CCTV Camera Pros has documented specific dynamic DNS setup instructions for LinkSys and D-Link routers. The instructions are based on certain models, but are likely the same or close to the same for other models of D-Link and LinkSys routers. If you need specific instructions for you router, please consult the manual that came with your router and look under the section for DDNS or Dynamic DNS.
